WEFT-REPLENISHING LOO'M.

To all whom it may concern:

Be it known that I, EPPA H. RYON, a citizen of the United States,residing at Waltham, in the county of -Midc nesex and State ofMassachusetts, have invented cercarry'a new group of tain new and usefulImprovements in Weft- Replenishing Looms, of which the following is'aspecification.

My invention relates to weft replenishing looms of the type shown anddescribed in U S. Letters Patent, No. 939,326,'and No. 951,659, and moreparticularly to improvements in the weft replenishing, or transferringmechanism, combined with looms of the typ referred to. 2

In the weft replenishing looms above referred to, a magazine'of a rotarytype is used, in which the bobbins or filling carriers are arranged in.groups. The dilferent groups contain filling carriers of differentcolors or characters, which correspond to the colors or characters ofthe filling on the bob.- bins in the shuttles used in the loom. In thisinstance my improvements are shown in connection with aloom havin fourshuttles, and the magazine is moved positively, and in unison with theshifting shuttle boxes at the .opposite' end of the loom, at each changeof position of the shuttle boxes, preparatory to supplying the activeshuttle with a fresh bobbin or filling carrier, on. the substantialexhaustion of filling thereon. After a bobbin or fillin carrier hasbeenremoved from one groug in the magazine, the: magazine is moved tobobbins or Lfilling 'carriers into operative osition.

The object ,of my invention is to improve upon the operating mechanismof the rotary magazine, by means of which the magazine is-moved'fromonegroup of bobbins or filling carriers to the next group, whichmovement, through my improved mechanism, takes place only after apredetermined bobbin of each group has been removed from the magazineby-the transferrer, and does not take place onthe transfer of anyotherbobbin of a group.

Myinvention consists in certain novel features of construction of myimprovements as will be hereinafter fully described.

I have only shown in the drawing a detached portion of a weftreplenishing loom of the type above referred to, with myimprovemcntscombined therewith, sufiicient Specification of Letters Patent.Application filed march 25, 1912. Serial No. 685,917.

Referring to the drawing:Figure 1 is an end view of a detached portionof a weft replenishing loom of the type referred to, with the rotarymagazine shown in section, and my. improvements combined therewith, and,Fig. 2 corresponds to vFig. 1, but shows some of the parts shown in Fig.1, in a different position; some of the parts shown in Fig. 1 are leftoff in this figure. a

In the accompanying drawing, 1, Fig. 1, frame, 2 is the lay, and 3 thestationary shuttle box, having a shuttle 4 therein, carrying-afilling'carrier .or bobbin 6, Fig. 1, is a stand rigidly secured to the. loomside 1. The stand 6 has the cylindrical portion 6, with a centrallylocated and hori-n zontal ly extending bolt 7, to loosely receive thesleeve hub 8 of an outer ring, not shown. for the tips of the bobbins5.- The heads of the bobbins or filling carriers 5 are mounted inpockets 9 on the inner ring 9, which ring is rigidly connected with theouter ring by the transverse rods 10, in the usual way.

A worm gear 1 l is mounted in this in stance on the sleeve 8,-and mesheswith and is driven' by aworm 12, secured on the upper end of avertically extending shaft-13. The lower end of the shaft 13 extendsloosely through a bracket or hearing 14, attached totheloom side'1,'s'eeFig. 1. 4

The transferrer 15 has the downwardly extending arm 15,..which isadapted to be operated by a dagger or hunter-on the'lay,

not shown, or otherwise. 1A horizontally extending arm 16, see Fig. 1,pivotally mounted on a stud 1G, is adaptedto engage with its forked endtwo collars 17, see Fig.

:2, on the vertically extending shaft 13, to move said shaft up anddown, according to the position of the shiftingshuttle boxes, not shown,onthe opposite end ofthe loom.

A rod head 18, Fig. 1, is pivotally con nected to the lever 16, and arod 19 extends upwardly from said rod head 18. and through :1 lug 20 ona stand.20, secured to the loo1n sidc,.see Fig. 1.. A helically coiledexpansion spring 21 encircles the rod 1%), and acts to more downwardlythe lever 16. The upper end of the rod 19 has connected there'- to oneend of a chain 2'2, which passes over a i guide sheave 23, mounted onthe stand 20,

- "shaped portion 13 thereon, which moves lon- 'and'to ,a patternmechanism, notshown, on -theoppos1te end of the loom.

- The vertically moving shaft113 has a square 'gitudinally in anelongated hubof the bevel pinion 24,- which pinion meshes with and isdriven by thetoothed portion, not shown, of.

the bevel: gear .25,1wh ich'has its hub loosely mounted on a'stud 25.Thebevel gear 25 has four notches25 therein, in which is adaptedto'extenda projec'tion'26 on a pawl 26, see ig. 2. The hub of the pawl26 is, loosely mounted-on a stud-27, on a stand, not

. 'shown' The stud 27 has also mounted there:

on the hub 28' ofia downwardly extending latch or pawl 28, which has aprojection 28'.

pawl-26, and acts to yieldingly hold either one of the pawls 26 and 28in their lockingthereon; which is adapted toextend into 'atendingprojection 28 on the latch 28, and-- at its other end against ,a lug 26on the position, as shown in Fig.2.

"." T-lie pawl 26 has a side extension 26 there din-which engages withthe end'of a shield.

- 3.0,t(;i hold saidshield in its inoperative po- "s'itiof1. 'The hub ofsaid shield 30 is loosely mounted onthe elongated hub of the bevel gear25. Extending downwardly from the hub of the shield 30 is an arm 30,which carries at its. 'end \30, a spring actuated- '-plunger 31, whichextendso'ut from its cy- .ljiulrical holder 30 to engage the ratchetportion on the bevel gear 25, to move said ear, through the movement ofthe rod connected with the arm 30, one-fourth -ofsits revolution, whenthe awl 26 is raised,

to'frevol've the'upright slPa 1 8, and toturn the magazine from onegroup of bobbins to another group. All ofthe above mentioned parts maybe of the usualand well known construction, and as shown and describedin U. S. Letters Patent, No. 939,326, andNo. 951,659, above referred'to.,

I will now describe my improvements, which consist of means to raise thehold fast pawl 26, .at the time when the'vertically moving shaft 13' isin its upper position, which may be when the upper box of the shiftingshuttle boxes is on a -level with the race-way of the lay. 5

The vertically moving;rod- 13'has adjustably secured thereon a. collar;-32, by a set screw 32. The collar "32 "is provided with a circular disk32", which is adapted, on the upward movement of the rod or shaft 13, toengage the end of a lever 33.;The lever 33 is pivotally mounted on astud34, at the npperforked end 35 of a fvertica'lly extend- .1. shield3.0,,to allow said shield 30- to be operside 1,.see Fig, 1.

1.2 The lower end of the bolt 35 has an eye:

35?, which has connected thereto the upper end of a chain 37.- The lowerend of the ja bracl'retor bearing 36, secured to the loom chain 37isconnected to the pawl 26. A sec-' From the above description inconnection with the drawing, the, operation of my im p ovell'lents bereadily those skilled in the art, and briefly is as follows :On theindication of the substantialexhaustion of filling on a bobbin in theactive shuttle, the transferr'er arm 15 is operated in the usual way, totransfer a bobbin 5 from the magazine into the active .ShllttlB 4, andas the vertically moving rod 13, according-to the position of theshifting shuttle boxes, has been moved to its highest position, asshown, in Fig. 1, the lever 33 will engage with its end the circulardisk 7 32 on the c'ollar32, and through the operation of thetransferrerarm l5, and intermediate connections to the lever 33, the

pivot point 34 of said lever 33 is raised, and also the pawl 26. israised, as shown in Fig. The,.pawl 26 is disengaged from the atedthroughthe rod 30" connectedjto a team lever, not shown, and through the springactuated plunger 31 engaging a ratchet portion 25 on the bevel gear 25,the

bevel gear 25 is moved, and through its rotation, turns the pinion 24,and also the upright shaft 13, and as the worm 12.0n said shaft 13 is inmesh with the worm gear 11 of the magazine, the magazine will be rotatedone-eighth of its circumference, to carry a new group of bobbins orfilling carriers 5 under the transferrer. arm 15,- after the transfer ofa bobbin.

' On thetransfer of another bobbin in the same group, as shown in Fig.2, the circular disk 32" on the uprightshaft 13, hasnot been moved highenough to engage and move the end of the lever 33, and the transferrerarm 15 will, through its connection to said lever 33, rock said lever,without raising its pivot point 34, see Fig. 2, thus leaving the pawl 26at rest, to hold the shield 30 in its inoperative position, and not movethe magazine to another group of bobbins.

It'will be .understood that the' details of construction of myimprovement-s may be varied if desired, and=that the magazine may bemoved to another group of bobbins, at the lowest,position of thevertically moving rod 13, instead of at the highest position. Havingthusdescribed my invention, what I claim as new anddesire to secure byLet ters Patent is 1. In a Weftreplenishing loom, a movable magazine,having bobbins or filling carriers of different color or characterarranged in groups, a transferrer, and means to move the magazine tobring a fresh group of bobbins under thetransferrer only on the transferof a predetermined bobbin of a group into the active shuttle. i

2. In a Weft replenishing 100111, a movable magazine, having bobbins 0rfilling carriers of different color or character arranged in groups, atransferrer, and means to move the magazine to bring a fresh group ofbob bins under the t-ransferrer only on the transfer of'a predeterminedbobbin of a group into the active shuttle, and eoni'iectiens iii--terinediate said transferrer and said means 3, In a Weir replenishingloom, a movable magazine, having bobbins or filling carriers ofdiiierent color or character arranged in groups, mechanism to more saidmagazine to bring fresh group of filling carriers in position raider tietra-nsferrer and said transife 1'61, to cause an one of the fillingcarriof a group to be transferred into the active shuttle at the propertime, means to cause the op" tion of said mechanism, said meansoperating on the transfer of one or more of the predetermined bobbins ofa group, and not operative on the transfer of the other bobbins of agroup.
